System memory System memory guidelines The PowerEdge R750 system supports DDR4 registered DIMMs (RDIMMs), Load Reduced DIMM (LRDIMMs), and Intel Persistent Memory 200 series (BPS). System memory holds the instructions that are started by the processor.
Figure 103. Memory channels Memory channels are organized as follows: Table 44.
General memory module installation guidelines To ensure optimal performance of your system, observe the following general guidelines when configuring your system memory. If your system's memory configurations fail to observe these guidelines, your system might not boot, stop responding during memory configuration, or operate with reduced memory.
NOTE: Intel Persistent Memory 200 series (BPS) cannot be mixed with 256 GB LRDIMM. ● Mixing of DDR4 DIMM types (RDIMM, LRDIMM, and 3DS LRDIMM), within channels, for Integrated Memory Controller (iMC), or across sockets are not supported. ● Mixing of Intel Persistent Memory 200 series (BPS) operating modes (App Direct Mode, Memory Mode) is not supported. ● If only one DIMM is populated on a channel, then the DIMM should always be populated in the first slot in that channel (white slot).
